Effects on NaeI-DNA recognition of the leucine to lysine substitution that transforms restriction endonuclease NaeI to a topoisomerase: a model for restriction endonuclease evolution.

Substituting lysine for leucine at position 43 (L43K) transforms NaeI from restriction endonuclease to topoisomerase and makes NaeI hypersensitive to intercalative anticancer drugs. Here we investigated DNA recognition by Nael-L43K. Using DNA competition and gel retardation assays, NaeI-L43K showed...
